Title: Hydraulic seal for a turbocharger
Inventor: PURDEY MATTHEW J
IPC: F01D11/04
Filed: 2007-11-26
Abstract: A hydraulic seal is defined between a rotating member such as a turbocharger shaft and a stationary member such as part of a bearing housing of a turbocharger. The members define a projecting annular disc that is received in an annular channel that is filled with hydraulic sealing fluid such as oil. Rotation of the rotary member applies a centrifugal force to the fluid thereby ensuring that it is retained in the channel between walls thereof and the disc. This annulus of fluid provides a hydraulic seal around the shaft between the bearing housing and the compressor or turbine housing. The oil is delivered into the channel from a supply in the rotary member. One of the walls of the channel serves as a weir whereby when the channel has an excess supply of oil is overflows the wall and passes the drain. The arrangement provides a seal against blow-by across the turbine end seal and restricts gas flow from the high pressure regions of the compressor and turbine housings into the low pressure area of the bearing housing.

Title: Improvements in or relating to sliding doors
Inventor: HARBORD FRANCIS
IPC: E06B3/46
Filed: 1956-04-03
Abstract: 809,132. Door operating mechanism; fastenings operated from a distance. DUBLIN PURE ICE & COLD STORAGE CO. Ltd. Dec. 17, 1956 [April 3, 1956], No. 10132/56. Classes 44 and 65(1) A sliding door, for refrigerators, kilns, &c. has roller mounting means arranged to accommodate a small, seal breaking movement away from the door frame and subsequent sliding movement in its own plane. The door 1, shown in its closed position, hangs by rollers 2 from a beam 3 which is itself roller mounted on brackets 4 attached at right angles to the door frame. To open the door a threaded shaft 7, mounted on the beam, is rotated by belt or gear drive from an electric motor to move a co-operating nut 8 to the left. The nut operates a bell crank lever 11, pivoted to the door, to rotate, via members 13, 14, the four cranks 17 thus forcing the door from its frame by means of locking arms 12 which are pivoted to the crank pins 18 and engage U brackets 20 on the frame. On further rotation of the cranks the fingers 21 lift the arms clear of the U brackets. Continuing movement of the nut first operates the lever arm 22 to disengage a safety catch 23 from the beam, and then engages pawl 26 to slide the door towards its opens position. At the end of the door opening movement the pin 27 strikes arm 26b to withdraw the pawl from engagement with the nut, the latter then operating limit switch 28 to stop the motor. To close the door the motor runs to move the nut to the right, sliding the door by means of pawl 26a, until the latter is withdrawn by the arm 26b striking the pin 27a, releasing the safety catch arm, operating lever 11 to cause arms 12 to engage the U brackets and draw the door towards the door frame, and finally operating limit switch 28a to stop the motor.

Title: Improvements in or relating to methods of and apparatus for indicating or recording a repetitive electric signal intermixed with interference
IPC: G06F17/00
Filed: 1962-03-16
Abstract: 949,354. Encephalographs. MNEMOTRON CORPORATION. March 16, 1962 [March 17, 1961], No. 10266/62. Heading A5K. [Also in Division H4] Relates to apparatus for indicating or recording repetitive electrical signals intermixed with interference and is described in relation to electro-encephalography but has other applications such as the analysis of radar signals. As shown in Fig. 1, a lamp 11 is operated through a trigger 18, also controlling the generator 17, and the resultant electrical response 12 in the brain of a human subject is detected at 13, amplified at 14, and at 15 is converted into a frequency-modulated pulse train, the mean repetition frequency of this pulse train being, for example, 100 kc/s. The timing pulses from the generator 17 have a considerably lower repetition frequency than the pulses from 15 and it is arranged that the lamp is activated after, for example, every four hundred pulses from 17, the light stimulus being repeated for a considerable number of times so that the wave response likewise is repeated. The frequency-modulated pulse train 16 is fed to a computer 19, Fig. 2, which is provided with four hundred memory locations (addresses) m 1  &c., means being provided for counting the pulses stored in each address and storing the count thus accumulated. An address selection system S is controlled by the timing pulses from 17 so that each time a pulse is applied, the pulses 16 are directed to the next consecutive store. When the first stimulus occurs, the train of four hundred timing pulses is supplied to the selector S so that the first pulse directs the signal pulses to memory m 1 , the second pulse directs them to m 2 , and so on, the stimulus being repeated two hundred times. The pulses thus accumulated and counted are read out as required through a device RO which converts the numerical value in each store to a voltage of corresponding magnitude, the device being controlled by timing pulses to step consecutively from memory channel to memory channel. The read-out values are recorded at 20 as by a pen recorder or alternatively may be displayed on a cathode-ray screen CR. Since the repetitive signal responses accumulate at the same time position after each stimulus whereas the noise is random, by accumulating a large number of responses the signal is accentuated with respect to the noise.

Title: Improvements in or relating to printing machines
IPC: B41F13/36
Filed: 1948-04-13
Abstract: 649,153. Printing-machines. LEATHLEY PUBLICATIONS, Ltd., and SCHUENEMANN, C. E. April 13, 1948, No. 10279. [Class 100 (ii)] Tripping-arrangements.-A cylinder trip for a printing couple comprises a sun wheel and an internally-toothed ring both engaging an intermediate planet wheel and both provided with locking devices permitting uni-directional rotation in opposite directions, the planet wheel being moved by a pivoted lever, biassed in contact with a cam driven by the machine main shaft but normally releasably held inoperative against the bias force, either the sun wheel or the toothed ring being rigid with a rotary release shaft whose intermittent movements, produced as the pivoted lever is rocked by the cam, are used alternately to apply and release the printing pressure. As shown, a main shaft 3, driving an impression cylinder 9 and an engraved copper &c. intaglio printing cylinder 10 through equal gears 5 ... 8, carries a cam 21 against which a roller 22 on the lever 23 is pressed by a spring 24 whenever a hand-, foot or solenoid-operated latch 25 is withdrawn ; the lever 23 is linked to a rotatable spider 29 carrying one or more planet wheels 31 meshing with a sun wheel 30 and a ring 32 ; the sun wheel is fixed to the release shaft 18 and anti-clockwise rotation thereof is prevented by spring pawls 19, 20 engaging discs 16, 17, while clockwise rotation of the ring 32 is prevented by a spring pawl 33 engaging ratchet teeth on the ring. Rods 14, 15 connect the discs 16, 17 to the eccentric bearings 12, 13 of the cylinder 10 so that rotation of the rod 18 produces a 60 degree oscillation of the bearings. In operation the latch 25 is momentarily withdrawn to allow the lever 23 to follow the cam 21 for one revolution, thus producing first a 90 degree anti-clockwise rotation of the ring 32, then a 180 degree clockwise rotation of the shaft 18 whereby the bearings 12, 13 will be rotated anti-clockwise from the printing position shown to the release position ; a further withdrawal of the latch 25 results in another 180 degree clockwise rotation of the shaft 18 to return the bearings 12, 13 to the printing position.

Abstract: 701,603. Agricultural implements. FORD, W. R. April 21, 1952 [May 4, 1951, No. 10581/51. Class 6 (1) The plough shares of a tractor-drawn one way plough are disengaged from the ground by the slewing action of the tractor when turning at the end of a furrow. As shown the ploughshares are mounted on a frame 10 rotatable about a beam 1 supported on rear wheels. The beam 1 carries a cross-member 3 coupled to the tractor by a cross axle 6 mounted in slots 8 which allow the tractor to be slewed relative to the plough. Chains 15, 17 anchored on the tractor frame are attached to a member 21 fixed to the frame 10 and are sufficiently slack to allow the frame to be rocked to bring one of the sets of ploughshares into position for ploughing but when the frame is moved to one of these positions the slack of one of the chains is taken up. When the tractor is slewed at the end of a furrow the pull exerted on the tightened chain will rock the frame to the intermediate position where both sets of ploughshares are raised. The frame is locked in this position by a control lever until it is released by the driver for the purpose of lowering one of the sets of ploughshares into position for ploughing. In a modification in which two sets of ploughshares are carried on separate frames, the pull of each chain may be transmitted by means of pulleys or a bell crank lever on the main beam to the appropriate frame so that the ploughshares or set of ploughshares carried thereby is lifted according to the direction in which the tractor is turned. The plough may be supported by wheels at its front end if so desired.
